All right, who keeps telling us that white is all colours and black is the absence of colours. If I mash all my colours one on top of each other I invariably get a dark black mash - I have never gotten white - even if I melt down wax crayons into completely blended mess (ask my mom about that one).

I think this must be one of the <lies to children> that are often told when there is no understandable explanation.
